MOTOR-VEHICLE LAMP.

:-..App1ication filed May 25,

Theinvention is a lamp for motor vehicle head lights or the like, in which the lower portion of the reflector is removed and in which a reflector shield is placed over the upper portion.

The object of the invention is to provlde a reflector for lamps which ehminates the upward or glare rays and concentrates the remaining rays downwardly;

Another object of the invention 1s to provide a reflector that is only placed in the upper portion of a lamp, and that only reflects rays downwardly.

And a still further object of the invention is to provide a lamp of a simple and economical design which presents a neat 'ap-- pearance and which reflects rays of light downwardly, only. i

WVith these ends in View the inventlon em-- bodies a casing which is somewhat elongated, a lense in the front of the casing, and a reflector which is curved upward from the base of a lamp that may be placed in the center of the rear of the said casing and then curved downward and forward to about the center of the said casing.

Other features and advantages of the invention will appear from the following de scription taken lILCOIlIlGOtlOIrWIth the draw-- ings, wherein':-

Figure 1 is a longitudinal sect on through the lamp casing and reflector.

Figure 2 is a rear view of the said lamp casing, showing a yoke in which 1t is adjustably supported.

In the drawings the device is shown as it would be made, wherein, numeral 1 indicates the reflector, numeral 2 the outer casing, and numeral 3 the adjusting nut.

The reflector 1 is a slightly distorted semispherical piece of material with a comparatively sharp curve at the rear and a somewhat fiattened curve at the front, as shown in Figure 1. The lower edge of the rear extends downward beyond the center to the point 4, and the lower edge of the front stops at the center line of the lamp casing, as shown at the point 5. At the rear of the reflector is a lamp socket 6 which may be placed on an angle as shown so that it will hold the lamp bulb in an upwardly inclined position.

The lamp casing 2 is made as shown in Figure 1, with the forward part extended to accommodate the froward section of the re flector. .This casing is provided with a cap 1926. ser1a1,no,.-111,4s1.

7 for holding a lens 8, and it is understood that both the cap and lens may be of any suitable design and arranged in any suitable manner. At the sides of the casin are pins 9 and 10 by which it is supporte in hubs 11 and 12 of a yoke 13. Thehub 12 is provided with teeth 14: that engage similar teeth 15 in a boss 16 at the base of t e these teeth may be held into engagement by pin 10, and it will be observed that the adjusting nut 3, which is threaded on the of the lamp in the reflector, and still another may be in the use of the reflector in a of a different design.

The construction will be readily understood from the foregoing description; To use the device it may be arranged as shown, and it will be observed that as the lower portion of the reflector is omitted all of the glare rays from the lower portion of the reflector will be eliminated and all of the reflected rays of the-lam will be reflected downward. It will be 0 served that when this device is used as a motor vehicle headlight it will be absolutely impossible for the operator of an approaching vehicle to see any reflected rays from the lamp, while at the same time practically all of the light. of the lamp will be reflected upon the roadway. The lamp may also be adjusted to permit any desired amount of the light to be reflected upon the roadway. This will, therefore, provide a lamp in which all glare rays will positively be eliminated.

Having thus fully described the invention, what I claim as new and desire to secure by Letters Patent, is a In a lamp of the class described, a lamp casing. a lens at the front of the casing, a substantially semi-spherical reflector in the upper portion of the casing, and a lamp bulb casing in the rear of the said reflector, the forward edge of the said reflector being, positioned at a point approximately on the horizontal center of the lamp casing and curving backand the sides of the said reflector curving ward and upward within the casing to a 'downward to the 'lower edges thereof on lines 10 point approximately at the top thereof and connecting the forward and rear points of then curving backward and downward with the said former curvature.

. 5 a somewhat sharper curve to a point slightly In testimony whereof he aflixes his sigbelow the horizontal center of the casing mature. said curvature forming a line on a vertical plane through the center of the said reflector Q ELISEO ZALLOCCO.
